— Add file fts3_icu.c to the amalgamation. Because of the way header files are included into sqlite3.c, fts3_icu.c has to appear after all the other fts3 and icu extension files. Ticket #3398. (CVS 5741)

#!/usr/bin/tclsh
#
# To build a single huge source file holding all of SQLite (or at
# least the core components - the test harness, shell, and TCL
# interface are omitted.) first do
#
# make target_source
#
# The make target above moves all of the source code files into
# a subdirectory named "tsrc". (This script expects to find the files
# there and will not work if they are not found.) There are a few
# generated C code files that are also added to the tsrc directory.
# For example, the "parse.c" and "parse.h" files to implement the
# the parser are derived from "parse.y" using lemon. And the
# "keywordhash.h" files is generated by a program named "mkkeywordhash".
#
# After the "tsrc" directory has been created and populated, run
# this script:
#
# tclsh mksqlite3c.tcl
#
# The amalgamated SQLite code will be written into sqlite3.c
#
# Begin by reading the "sqlite3.h" header file. Count the number of lines
# in this file and extract the version number. That information will be
# needed in order to generate the header of the amalgamation.

{/******************************************************************************
** This file is an amalgamation of many separate C source files from SQLite
** version $VERSION. By combining all the individual C code files into this
** single large file, the entire code can be compiled as a one translation
** unit. This allows many compilers to do optimizations that would not be
** possible if the files were compiled separately. Performance improvements
** of 5% are more are commonly seen when SQLite is compiled as a single
** translation unit.
**
** This file is all you need to compile SQLite. To use SQLite in other
** programs, you need this file and the "sqlite3.h" header file that defines
** the programming interface to the SQLite library. (If you do not have
** the "sqlite3.h" header file at hand, you will find a copy in the first
** $cnt lines past this header comment.) Additional code files may be
** needed if you want a wrapper to interface SQLite with your choice of
** programming language. The code for the "sqlite3" command-line shell
** is also in a separate file. This file contains only code for the core
** SQLite library.
**
** This amalgamation was generated on $today.
